Researchers in the organizations such as the University of Munich, Germany found that in terms of the semiconductors for LEDs, sizing semiconducting nanocrystals differently can make them emit various colors of light. The color range of emitters covers from blue light to visible red light, all with high color purity.
Researchers developed a method to use low-cost material perovskites for producing semiconducting crystals based on different requests. Its core is a nanometer-thick film composed of nanoporous materials, which contain silicon and aluminum oxide. The materials feature numerous pores where chemical reactions occur. The solution reacts in the pore and produces perovskite nanocrystal.
Experiments show that the pore size on the film directly influences the size of nanocrystals which further decides the color of the light. By using this method, the nanocrystals can be very stable that make LED reach higher color fidelity.
Researchers stated that they would further enhance the efficiency of this color tuning technology and broaden its reach to more applications, implying the color tuning for flexible full-color displays.
